I applied through an employee referral. The process took 5 days. I interviewed at Cenergy International (Houston, TX) in July 2014
Interview
They interviewed me twice in the same day with three people. The first time, one of them was in a meeting, so I met with the department head and the head of HR. I got about 5 miles away and they called me back to meet with the original two plus the COO. The interview went very well and I got an offer the same day.
